Re encode with lower bit rate.

Is that video or movies format mp4 that accepted by your MP4 player? now, i suggest to use this powerful video converter that easy convert any video formats to mp4 that play on your mp4 movie player.

Each of the AVCHD camcorders ships with software designed to playback the files on your computer. Sony's HDR-SR1 and the newer HDR-SR5 both record video in the AVCHD format and ship with the Picture Motion Browser, which plays back AVCHD files on most computers. If you purchased one of the Panasonic AVCHD camcorders, the included HD Writer should allow you to playback video recorded with your camcorder.
  

While the bundled applications work, my personal preference, is Cyberlink PowerDVD Ultra, which supports playback of the AVCHD files and a whole host of other high definition formats. In addition to playing back your HD camcorder files, PowerDVD Ultra plays back Blu-ray and HD-DVD disks (with the accompanying drives connected, of course). PowerDVD Ultra also makes it possible to expand your HD video editing options, by using the included codecs to render the AVCHD video in apps like VirtualDub.

Cyberlink PowerDVD ultra can be downloaded from here :
